Technical data sheet
PrintMethod description
A homogenous portion of the sample is mixed with water containing an internal standard. It is heated in a heating block for a specified amount of time, after which a sample of the headspace over the mixture is taken and injected into the gas chromatograph. The hexanal released into the headspace is quantitated via comparison of the hexanal gas’s chromatographic response to that of the internal standard.
Acceptable matrices
The method is applicable to a variety of food products, including cereals, snacks, dressings, and frostings.
Limit of quantitation
The lower detection level is 0.3 ppm (parts per million); with an upper limit of 50 ppm.
Equipment
Gas Chromatograph with Flame Ionization detection
Method reference
Internally developed method
Reportable unit
ppm (parts per million)
Sample size requirements
20 grams
Information required by submitter
The sample must be kept cool/cold to minimize fatty acid oxidation.
Additional information
Hexanal is a by-product of fatty acid oxidation and this method measures the amount of hexanal in food products and ingredients. Therefore, this gives a measurement of the level of oxidative rancidity for oil in a food product.
Common Hexanal Test Testing Questions
While our sales and customer service team are happy to answer general testing questions, consultations typically start at a rate of $250 per 30 minutes regarding the interpretation of reported test results or questions about our test methods. We cannot consult on regulations, tolerance limits, or claims.
We make every effort to keep our methods and detection limits up to date according to the latest standards and qualifications. If you have any questions regarding the limit of detection/quantification or method references, please contact our Customer Service team at 1-800-245-5615.
Our standard turnaround time is 10 business days for most assays. There are some assays that require a longer turnaround time. We also offer a RUSH service that is half the time of the standard turnaround time of the assay at double the cost of the assay. A few assays that we provide cannot be rushed due to the nature of the test. Please check the specific assay you are interested in regarding the ability to RUSH the turnaround time.
